spss-sav-pseudonymization

A command line utility that replaces numeric identifiers in a given SAV file column with randomly chosen numbers using a UUID generator. Output of this program is a new SAV file and a file containing the mapping between old and pseudonymised numbers. This mapping can be reused by pointing to it via an input parameter.
